TRANSFORMATION PROCESS OF THERMOPLASTIC POLYURETHANES BY EXTRUSION, AND MODIFYING AGENTS USED IN SAID PROCESS

摘要

the present invention relates to a method of processingby extrusion of compositions based on polyurethaneplastic (tpu), characterized in that it adds 5up to 45% by weight of one or more agents that modify a relationthe tpu, the officers would be selected from among the modifiersthermoplastic elastomers based on polyestu00e9ramides orin polyu00e9theramides excluding styru00e9niques resins. thesesuch agents are parameters that modifytransformation and the rheological behaviour of the tpuat the time of their implementation.
